Forms
graso (feminine grasa, masculine plural grasos, feminine plural grasas)[1]
Etymology
It is inherited from Vulgar Latin grassus, from crassus (“fat, thick”), changed under the influence of grossus (“thick”).[2][3][1] The form with ⟨g-⟩ is already found in Late Latin authors such as Pelagonius in the 4th century.[3] García de Diego considers the reduction of ⟨cr-⟩ to ⟨gr-⟩ a normal sound change, and the influence of the other adjective unnecessary.[4] The learned doublet is craso, from 1550.[3][1]
Corominas finds the adjective rare and unpopular in Castilian, and suspects that it is not inherited but was formed late from the noun grasa, itself possibly of foreign origin though old.[3] Elsewhere the word is the usual one for “fat”: Catalan gras, Occitan gras, French gras, Italian grasso and Romanian gras.[3] Portuguese has only the rare adjective graxo, formed from graxa (“grease”), which like Catalan greix continues Vulgar Latin *crassia.[3][5]
The origin of the Latin adjective is unclear.[6][1] De Vaan rejects a link with a root meaning “to wind” and with crātis (“wickerwork”), and notes that it belongs to a group of adjectives for bodily shapes with a double consonant, such as flaccus.[6]
Earliest recorded meaning
The Old Spanish Textual Archive has 14 occurrences in five texts, the first dated 1385.[7] Corominas's first record is Alfonso de Palencia, who contrasts obeso, fat on the outside, with grasso, fat inside.[3]
Semantic evolution
The word is missing from Nebrija, Covarrubias and most medieval and classical authors.[3] Autoridades quotes Laguna's Dioscorides (1555) on oil „y todas las cosas grassas”, and Lope de Vega using grasso as a noun for “fat”.[3][8] In the Americas it is recorded from 1548, of fat used as an ointment and of fatty fish and oysters.[9]
Today it is used mainly in chemistry, biology and cooking (materias grasas, alimentos grasos, ácido graso) and of greasy hair or skin.[3][2] In Salamanca it is said of land still too wet to work.[10] The noun grasa, recorded from the first half of the 14th century, is far more common than the adjective.[3]
